Abstract: PURPOSE: To make it possible to detect always correctly the white peak and the black peak of the actual original by detecting the difference between the white level and the black level in a period other than high-reflection factor signal periods by a backboard signal circuit.  
     CONSTITUTION: A original is mounted on backboard 1, and the light is irradiated to the original, and the reflection light is converted photoelectrically by 2 and is subjected to AGC, thereby obtaining picture signals while holding the difference between the white peak and the black peak constant. Here, backboard 1 is constituted by materials having a reflection factor higher than the forecasted white part of the transmission original, and the signal period of this high reflection factor is sampled to detect the difference between the white level and the balck level in a period other than this signal period by backboard signal detection circuit 4. As a result, the white peak and the black peak of the actual original can be always detected correctly.

Title: Rotary power transmitting device having crank mechanism
Inventor: OOTSUKI AKIYOSHI
IPC: F16H21/14
Filed: 1987-04-09
Abstract: PURPOSE:To reduce consumable energy and improve a drive force by connecting a crank pin of a rotary shaft on an input side to a crank pin of a rotary shaft of an output side via a sliding arm rod, an original connecting rod, and a follower connecting rod. CONSTITUTION:When a crank pin 3 of a crank rotary shaft 2 on an input side begins to move, an original connecting rod 9 moves and causes a pivot 8 to slide on a circular locus centered on a shaft rod 6 by means of a sliding arm rod 7. As a result, a crank pin 5 is rotated by a pressing force and a tensile force of a follower connecting rod 10, which causes a crank rotary shaft 4 on an output side to rotate to transmit rotation to a rotary follower shaft. Namely, if the rotation of the crank pin 3 starts moving from a bottom dead point (a), the position moves in the sequence a b c d a, and the rotation of the crank pin 5 of the rotary shaft 4 is transmitted to positions a top dead point a' b' c' d' a'. Repeating the above sequence, the rotation is smoothly transmitted.

Abstract: PURPOSE:To form an element isolation region by a method wherein, after a polycrystalline Si film is laminated on the surface of the silicon substrate, a phosphorus-silicate glass is made to grow in vapor phase for eliminating the roughness of the surface and for flattening the surface, and after that, a thermal oxidation is performed to oxidize parts of the polycrystalline Si film and the thermal oxide films consisting of both of the phosphorus-silicate glass and the parts of the polycrystalline Si film are chemically removed. CONSTITUTION:A thermal oxidation is performed on a silicon substrate 1 and a thermal oxide film 3 is formed on the surface of the silicon substrate 1. After that, when a polycrystalline Si film 4 is made to grow and the part of a groove 2 is completely filled with the film 4, a recess 5 is generated on the upper part of the groove 2. A phosphorus- silicate glass 6 is made to grow in vapor phase, a heat treatment is performed and the surface is smoothed. Then, when a thermal oxidation is performed in a high-temperature oxidizing atmosphere and parts of the polycrystalline Si film, which exist on the places whereon the groove 2 does not exist, are all oxidized, the parts are oxidized while holding the same height and the interfaces between the oxide films and the substrate 1 become flat over the whole surface of the silicon substrate 1. An etching is performed on the thermal oxide films consisting of the phosphorus-silicate glass 6 and the parts of the polycrystalline Si film 6 using solution to remove the thermal oxide films and parts 10 of the surface of the silicon substrate 1, whereon the groove 2 does not exist, are made to expose. By this way, the groove part to be filled with a polycrystalline Si film 8 is turned into an element isolation region 14.

Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To check any nick due to a hot crack by using a CBN sintered body, making thermal conductibility and a coefficient of thermal expansion into a specified range each, as a cutting edge. SOLUTION: A CBN sintered body in a range of more than 3.0 and less than 4.0×10<-5> /K in the range that thermal conductivity at 129 deg.C is more than 400 W/m.K and a coefficient of thermal expansion ranging from 20 deg.C to 600 deg.C in temperature is used as a cutting edge. With this constitution, in time of high speed milling cutting, heat to be produced in an interval of contact between this cutting edge and a work material is able to be efficiently set free through the whole sintered body. In addition, thermal expansion in the sintered body in and around the cutting edge is a little, and since the heat moves into the whole sintered body, a temperature gradient lying between the cutting edge and the sintered body inside is also a little, whereby a tensile stress attributable to a thermal expansion difference comes to be reduced in consequence.

IPC: G06F9/44
Filed: 1985-04-24
Abstract: PURPOSE:To perform the unification processing at a high speed by initializing only a desired part of a variable area only in case the unification processing is successful. CONSTITUTION:A variable area for a main clause is secured in an execution process if a function F is called out of a name list. Then the head clause is extracted and the unification is performed for the head part P(a, x) 4 of the clause in the order of the 1st subtraction number 'a' and the 2nd subtraction number 'X' is equal to an uninitialized conversion cell (N cell) and therefore it is supposed that the corresponding variable area X is not defined in the unification mode when the initialization is carried out. If the unification is successful at the head part, the variable cell corresponding to a variable Y is initialized, i.e., undefined. Then the main body parts q(X, Y) and r(Y) are called out.

Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To give an extension period so that a gas concentration signal can be sufficiently created and to prevent a detection miss from occurring by extending a detection period as much as a prescribed time and continuing to detect gas concentration when detected gas concentration reaches a prescribed first stage alarm level during gas concentration detection period. SOLUTION: An alarm level detecting means 16 generates a 1st mode heating signal 16a which heats a sensor element in a low temperature area during a 1st gas concentration detection period. Also, it extends the detection period of this time as much as a prescribed period when gas concentration reaches a prescribed first stage alarm level during the 1st gas concentration detection period. It has a function that generates a 2nd mode heating signal 16b which heats the sensor element in a high temperature area during the extension period. With this, it becomes possible to sufficiently generate a gas concentration signal 12a by giving the signal 16b that corresponds to an extension period to a heating part 122 for a 2nd gas 11B which has slow output responsiveness like methane gas.
